FAQs
Ensure proper enclosure integration with a 2" trade size footprint and a 100A frame. Connect three wires in a four-pole arrangement, verify grounding with Style 2, and confirm supply is 480 Vac/250 Vdc. Use the included interlock with the breaker to prevent live-arc exposure during maintenance. Follow NEC/CEC guidelines and mass procurement standards for hazardous locations.
It carries NEC/CEC compliance for hazardous and classified locations, with NEC Hazardous Rating covering Class I, Division 1, Class I, Division 2, Class II, Division 1, Class II, Division 2, and Class III. NEMA ratings include 3, 7, 9, and 12, ensuring robust protection in severe environments. UL certification is referenced in the product literature for interlocked receptacles with circuit breakers in hazardous locations.
Ideal for oil and gas, chemical processing, mining, and other heavy industrial settings where equipment operates in hazardous environments. It supports large motor and pump loads with a 60A rating and 480 Vac/250 Vdc supply, while the interlock ensures safe commissioning and maintenance without exposing personnel to live circuits.
The integrated circuit breaker within a 100A frame provides fast fault isolation and coordinated protection, reducing downtime during maintenance and improving overall system reliability. The interlocked design prevents breaker operation under unsafe conditions, delivering predictable performance in harsh environments.
Schedule periodic inspection of the interlock mechanism, door spring tension, and enclosure integrity to resist dust and washdown ingress. Verify continuity of ground (Style 2) and ensure the 60A breaker remains calibrated for the load. Keep the unit in accordance with NEC/CEC requirements for ongoing compliance and safety.
